SK D&D promotes a sound ethical culture across the company by operating ethics and anti-corruption training programs for all employees, including contract workers. In addition to mandatory annual legal trainings—such as disability awareness, workplace harassment prevention, and sexual harassment prevention—SK D&D offers a wide range of training curricula. These include guidance on using the SK Ethics Management Reporting System, case studies, and discussions on workplace misconduct. All employees participate in ethics training with a 100% completion rate each year, reinforcing the company’s ethical management awareness.

SK D&D also holds an annual Ethics Management Workshop to strengthen ethical awareness among all employees. These workshops facilitate cross-hierarchical and cross-functional discussions on proper decision-making in ethically challenging situations. In 2024, the workshop was conducted for 178 employees and executives by level and department, with approximately 96% participation. Additionally, to cultivate shared values and promote ethical practices, the company distributes a quarterly Ethics Management Letter and implements awareness campaigns such as prohibiting the exchange of gifts with business partners during holidays.

SK D&D operates a self-regulation system across its headquarters and subsidiaries to prevent corruption and unethical behavior in business activities. Departments responsible for key business areas autonomously monitor the current status of ethics risks.

SK D&D conducts regular annual ethics and anti-corruption risk audits at all operating sites, including headquarters and subsidiaries. In 2024, audits focused on the prevention and management systems for ethics and corruption risks within subsidiaries, including reviews of regulations, roles and responsibilities, and processes. When ethics or anti-corruption risks are identified through internal audits, the findings are reported to the Audit Committee. The Internal Control Department then implements corrective actions or works collaboratively with relevant departments to address and mitigate these risks.

To assess and improve the level of ethics management practices, SK D&D conducts an annual ‘Ethics Management Practice Survey’ for all employees and business partners. Since its introduction in 2015, the survey evaluates ethics practice levels, organizational ethics culture and systems, and types of unethical conduct. Based on the survey results, key areas for improvement are identified and used to enhance the company-wide ethics management framework and related activities. In addition, a ‘Supplier Ethics Management Survey’ is regularly conducted with business partners. In 2024, SK D&D reviewed ethics violations related to purchasing contracts among employees of 69 major suppliers and found no significant issues.

In 2024, SK D&D received a total of nine reports related to ethical management. These included cases involving unfair practices and abuse of power toward partner companies, lack of mutual respect among employees, improper handling of work duties, legal non-compliance, violations of internal regulations, and other customer-related complaints. Each report was thoroughly investigated through internal procedures, and appropriate actions were taken to address the issues. All reported cases were resolved and formally closed following the implementation of the necessary corrective measures.
